The only problem was, the sign contained a mobile number, which fans quickly realised belonged to the one and only Nick Kyrgios. Kyrgios commented on the post: “You are an absolute idiot, everyone stop calling me!!!!!”

The number was quickly disconnected after what most likely was a never ending hoard of phone calls and text messages.

Of course, not all of the birthday wishes directed towards him caused a headache, as many took to social media to say happy birthday in a much more conventional way.
